Lecture Seven
Poll Results Question 1: Do you support reforming the US
health care system so that it is a single payer system similar to that of Canada?
Choice 1: yesChoice 2: noChoice 3: I am undecided
Exam I Results Average = Standard Deviation = High grade = Scale:
A = B = C = D =
What to do if score was lower than you hoped? Come see Dr. RRK - Re-examine how you studied!! Can replace lowest hour exam with final exam
grade Extra credit announcements coming soon
Four Questions
What are the major health problems worldwide?
Who pays to solve problems in health care?
How can technology solve health care problems?
How are health care technologies managed?
Start here
How can we use science and technology to solve problems in health care?
Advance to next unit
How do we test and refine innovations? Case studies

Biological plausibility
Clinical Trials
Where do innovations come from?

Today:
The process of developing a new
medical technology
Class Activity #1 – Gene Therapy
Directions: Place the articles in correct chronological order
Contextual clues in the selections Your knowledge of the science of DNA and genes Your recollection of events in the media.
Articles reflect current thought for the time First article published in 1953; the last in 2003 Discuss in group; come to consensus Choose one member of your group to speak
Did your ideas about the sequence match each other?
What clues or events prompted you to make choice? Do not discuss your ideas with other groups
Definitions
What is the difference between science and engineering?
Definitions Science
Body of knowledge about natural phenomena which is:
Well founded Testable
Purpose is to discover, create, confirm, disprove, reorganize, and disseminate statements that accurately describe some portion of physical, chemical, biological world
“Science is the human activity of seeking natural explanations for what we observe in the world around us.”
Definitions Engineering
Systematic design, production and operation of technical systems to meet practical human needs under specified constraints
Time $$ Performance Reliability
“Engineering. . . in a broad sense. . . is applying science in an economic manner to the needs of mankind “
Definitions
What is the difference between science and engineering? Science
Inquiry to better understand world around us No practical goal necessary
Engineering Use of science to solve real world problem in
practical way
Engineering Design Method Fashioning a product made for a
practical goal in the presence of constraints
Six design steps: 1. Identify a need 2. Define the problem (goals, constraints) 3. Gather information 4. Develop solutions 5. Evaluate solutions 6. Communicate results
Papers, patents, marketing
Refine Design
SPECS
FMEA
Example: Ischemic Heart Disease
Science of IHD Engineering solutions for IHD
1. Identify a need 2. Define the problem (goals,
constraints) 3. Gather information 4. Develop solutions 5. Evaluate solutions 6. Communicate results
Journal Article
